A light bulb distributor was given a study from an LED bulb manufacturer showing that LED light bulbs are better for the environment than traditionalbulbs. Is there an incentive for this study to be biased? Why or why not?

Yes, because the LED bulb manufacturer may benefit from the survey results.

If the light bulb distributor will decide get more stock of LED bulb due to the study given by the LED company, then, the LED company will benefit from it.

Determine the lengths of the sides of the rectangle using the given area. Give answers both exactly and

Degger [83]

Answer:

Part a) Exactly values

The width of the rectangle is $\frac{\sqrt{70}}{2}\ cm$

The length of the rectangle is $2\sqrt{70}\ cm$

Part b) Approximately values

The width of the rectangle is $4.2\ cm$

The length of the rectangle is $16.7\ cm$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of rectangle is equal to

$A=LW$

we have

$L=4x\ cm\\W=x\ cm$

substitute the values in the formula

$A=4x(x)$

$A=4x^2$

$A=70\ cm^2$

$70=4x^2$

Solve for x

Divide by 4 both sides

$\frac{70}{4}=x^2$

square root both sides

$x=(+/-)\frac{\sqrt{70}}{2}$

The solution is the positive value

$x=\frac{\sqrt{70}}{2}$

therefore

Exactly values

$L=4\sqrt{70}}{2}=2\sqrt{70}\ cm\\\\W=\frac{\sqrt{70}}{2}\ cm$

Approximately values

$L=4\sqrt{70}}{2}=16.7\ cm\\\\W=\frac{\sqrt{70}}{2}=4.2\ cm$

Which package has a better price a 10 pack of 2.1 ounce bars which costs $15.37 or a 12 pack of 1.4 ounce bars which cause $15.3

jasenka [17]

Find which is a better package between the 2
10 pack of 2.1 ounce bar = costs 15.37 dollars
=> 2.1 x 20 = 21 there are a total of 21 ounce of bar
=> 21 / 15.37
=> 1.366 dollars / ounce

12 pack of 1.4 ounce bars = costs 15.35
=> 1.4 x 12 = 16.8, there are 1a total of 6.8 ounces of bar
=> 16.8 / 15.35
=> 1.094 dollars / ounce

Thus the second choice is the better package between the two. The 12 pack of 1.4 ounce bars.
